ARRI's M18 HMI Lamp Head With ALF/DMX Ballast Kit (Multi-voltage) is an open-face, lensless, more efficient lamp head built to work with a new power class of lamp--the 1800W SE HMI (not included), which has an average life of 750 hours, a luminous efficacy of 92 lumens/watt, and a Color Rendering Index (CRI) greater than 90 at 6000K. DMX control and ALF (Active Line Filter) together produce much more efficient power use in an already very efficient lighting fixture. The M18 combines the best aspects of a PAR and a Fresnel, creating diverging rays of light to produce a very crisp shadow. This fixture is supplied for use with 90-125/180-250VAC. This lamp has a beam angle (HPA) of 20 to 60°, with a wide usable field angle. The lamp head is silver.
